The cross walls are further characterized in each instance by theprovision of two.

24. The general form of the blank so folded is that of the letter W. Thefolds 22 occupy sets of means either or both of which coact with theblank to secure the cross walls lowermost positions, the folds 23 are adacent the upper edge of the carton, and the folds 24 are adapted tooccupy substantially 1h a l lelatloh hheewlth In the a center postion'when the blank is closed h p h Shown herem, P Wan over to provide coversfor the carton. The h w 1 Q m vertlcauy bends 21 are disposed betweenthe center from lts PP g? A flanhg entrance d b tt f ld 20 d 22, as h Thfor the slot is provlded by slantmg backat sections of the blank betweenthe fold 20 and 2' n g fl-a from the pp slot side a lug 53 pro ectspartly across the entrance to the slot. When a cross wall is bends 21provide a vertically extending double wall 0. Between the bends 21 and22 v inserted through the slots 35 into final position, its lug 53,which is bent laterally durare oblique sections d, between the folds 22ing this operation, will straighten out into the proximate slot 36 tooverlie the vertical folds 23 and 24 are cover sections f. Joined toeach cover section at the fold 24 is a flap and 23 are other sections 6,and between the g. In addition the blank is adapted to'be double wall 0.

slots are openings 36 arranged in a row along the lines 31 which definesbetween' rous product, may be as'follows: The carton is first doubledThe lugs 53 and slots 35 constitute one set of means for interlockingthe blank and cross walls. I provide also another set of interlockingmeans which serve additionally and independently to sustain theinneroblique sections of the blank intermediately in W- formation, asshown in Figs. 1. and 2. Such an interlock desirably includes each crosswall wherein are provided additional slots or incisions--65 in line withthe sections d of the blank. Interrupting the continuity of the slots 35of the blank are obstructing lugs 66 adapted to be received within theslots 65 of the cross walls when the latter are assembled in positionwithin the blank. By this means the cross walls are held in placeindependently of the interlock afforded by the co-operatin vlu s andslots 53 and 36, respectively, an ad itionally, the carton bottom ismaintained centrally throughout its length with the inner sections ofthe blank sustained intermediately in the W formation shown.

The operation of assembling the cross walls B in the carton blank A mayproceed upon itself along the fold line 20 so as to bring the two setsof slots 35 into register. The cross walls are'then inserted intoposition within these slots the lengthof which exceeds the verticaldimension of the cross walls, and the latter are then shifted lengthwiseof the blank slots so as to bring the double walled section 0 downtoward the lower end of the cross wall slot 51. During thismovement thedouble'walled section '0 of the blank may be required to bend whilemoving past the obstructing lugs 53. In the final position, theparallel-edges of the slots 51 afford support toopposite sides of thedouble walled section 0 such thatit is held against tilting. The lugs 53which project into the recesses 36 prevent a reverse movement of theblank relative to the cross walls, and the projection of the lugs 66into the slots cause the inner sections of the blank to be hooked upobliquely into the position desired for thesustaining of eggs or othercommodities.

With the walls assembled into the blank in this manner, the parts areinterlocked securely against displacement. For convenience in packingand shipping, the walls may be turned flat against the blank and in thisknock-down condition the carton occupies but very little space. It maybe set up for use by bending the blank along the folds 22.

which has the effect of bringing up the sections 6 and h until thelatter are hooked into the notches ll. With the parts so related, thelugs 46 act to retain the'outer sections of the blank in a set-upcondition with its upper sections f and 9 opened out to permit insertionof eggs or other commodities into the cells defined by the blanksections 03- and e and the intervening cross wiills. As these cells arefilled, the obliquely disposed sections 01 and 6 will tend to bow out,in so far as permitted by the interlocking lugs and slots 66 and 65,respectively, in conformity with the contour of the eggs or othercommodities so set. in place. The

upper" portions of the blank consisting of the sections f and 9 maythereafter be folded over the top of the carton, the "sections f meetingsubstantially along the center fold 20 so as to permit insertion of thetwo flaps g vertically into the slots 51 along one side of the doublewall 0.

.is afforded to the carton bottom such that the latter is adequatelysustained at an elevated point regardless of the load which may beintroduced into the carton. The

various longitudinal bends or folds in theblank provide, in effect, apluralityof hingedly connected strips forming side and bottom walls of atrough of which there are two, arranged side by side.

I claim:

1. An egg holder or filler in which is comprised a blank bent in theform of a letter W with slotted oblique bottom sect-ions meeting at anelevated point centrally of the holder, the blank also providing frontand rear sides and a cover,a plurality of cross walls collapsiblysupported within the blank and extended through the slotted bottomsections thereof, and coacting means on the cross walls and obliquecentral bottom sections for sustaining said oblique bottom sections at apoint intermediate per and lower edges.

2. An egg holder or filler having a slotted blank with longitudinalbends such that it may provide a cover, front and '"rear sides and abottom in which is comprised a pair of upwardly inclined transverselyslotted sections meeting centrally for the length of the holder; crosswalls extended vertically from the cover through the slotted bottomsections, and an interlock between the cross walls and obliquecentralbottom sect-ions for snstainingsaid inclined bottom sections at a pointintermediately of their upper and lower edges.

3. An egg holder or filler having a slotted blank with longitudinalbends such that it y of their upmay provide a cover, front and rearsides and a bottom inwhich is comprised a pair of upwardly inclinedtransversely slotted sections meeting centrally for thelength of theholder, cross walls extended vertically from the cover through theslotted bottom sections, and an interlock between the cross walls andinclined central bottom sections for sustaining said inclined bottomsections at a point intermediately of their upper and lower edges, saidinterlock comprising means interrupting the continuity of the slots inthe inclined bottom sections together with a complementary incision inthe cross Walls for receiving such 1neans.

4. An-egg holder or filler blank with longitudinal bends such that itmay provide a cover, front and rear sides /and a bottomin which iscomprised a pair of upwardly inclined transversely slotted sectionsmeeting centrally for the length of the holder, cross walls extendedvertically from the cover through the slotted bottom sections, andcoacting means on the cross walls and inclined central bottom sectionsof the blank for sustaining said inclined bottom sections at a pointintermediately of their' upper and lower edges, said means comprisinglugs on the one extended into lncisions in the other located between theupper and lower edges of-the inclined bottom sections and oppositelywith respect to the longitudinal center of the holder.

5. In a collapsible egg holder, foldable tro'ugh members arranged sideby side and having oppositely inclined slotted bottom sections-meetingin a ridge centrally of the holder, a plurality of cross wallscollapsible with the foldable trough members and ex- 40 tendedvertically through theinclined slotted bottom" sections, said crosswalls and trough members being so formed as to interlock at the ridgeand along the inclined central bottom sections below theridge. I

6. In an egg holder, trough members arranged side by side and meeting ina ridge centrally of the holder, said trough members having oppositelyinclined slotted bottom sections, cross walls extended verticallythrough the slotted bottom sections and formed to embrace the troughmembers across the ridge and to each side thereof, and coacting means onthe cross walls and oppositely inclined central bottom sections below 65the TM e for sustaining said sections in predetermined oblique relation.7. In a collapsible egg holder, trough members arranged side by side andmeeting in a ridge centrally of the holder, said trough members havlngoppositely inclined slotted bottom sections, cross walls extendedvertlcally through the slotted bottom sections and embracing oppositesides of said trough members adjacent the ridge, and coacting meansonthe cross walls and oppositely inhaving a slotted clined centralbottom sections for sustaining said sections in'predetermined obliquerelation. v t

8. A collapsible holder or carton for eggs comprising a blank foldablealong longitudinal scored lines to provide side. and top wall sectionsand bottom wall sections oppositely and downwardly inclined from a foldor ridge disposed centrally between the side sections, said bottom wallsections being transversely slotted, and cross wall partitionsextendedvertically through said slotted bottom sections and individuallyremovable therefrom, said cross Wall portions being configured at theircentral regions to interlock with said central fold or ridge and witheach of. said downwardly inclined bottom sections to each side of saidridge and intermediate said ridge and the lower edges of said inclinedbottom sections, whereby said cross wall partitions are securely heldagainst individual separation from the folded blank and the divergingbottom sections sustained in predetermined oblique relation centrallybetween the side walls. 0
